Salts can be easily identified, since they usually consist of positive ions from a metal with negative ions from a non metal. The salt we put on our fries is actually sodium chloride and is made up of metal Na1+ and non metal Cl1- ions. Often you will see this written as Na+ and Cl- (the 1 is dropped) or simply NaCl.
The manufacture of salt is one of the oldest chemical industries. A major source of salt is seawater, which has a salinity of approximately 3.5%. This means that there are about 35 grams (1.2 oz) of dissolved salts, predominantly sodium (Na+) and chloride (Clâ) ions, per kilogram (2.2 lbs) of water.alt is an essential nutrient and the amount of salt in the diet influences health. Too much salt can raise blood pressure and may increase the risk of heart attacks and strokes in susceptible populations.
